Question

match each of the following terms with its correct definition. extracellular water (click to select) intracellular water (click to select) ions osmosis molecular movement from a region of higher to lower concentration movement of a solvent, usually water, through a selectively permeable membrane water that is inside cells water that surrounds cells or is in blood elements or small molecules that have electrical charges water formed by cells as a metabolic by - product

Explanation:

• Extracellular water: As the name suggests, it is the water that is outside the cells. The description "Water that surrounds cells or is in blood" fits this as blood (extracellular fluid) and interstitial fluid (surrounding cells) are part of extracellular water.
• Intracellular water: Refers to the water within the cells. So, "Water that is inside cells" is the correct definition.
• Ions: These are elements or small molecules with electrical charges. For example, \(Na^{+}\) (sodium ion), \(Cl^{-}\) (chloride ion) etc. So, "Elements or small molecules that have electrical charges" is the right match.
• Osmosis: It is specifically the movement of a solvent (usually water) through a selectively permeable membrane. While molecular movement from higher to lower concentration is a more general definition (which is for diffusion).

Answer:

• Extracellular water: Water that surrounds cells or is in blood
• Intracellular water: Water that is inside cells
• Ions: Elements or small molecules that have electrical charges
• Osmosis: Movement of a solvent, usually water, through a selectively permeable membrane
